Velvet-throated songstress Nina Simone hypnotized audiences with her signature renditions of standards from the American songbook. But on September 15, 1963, a devastating explosion in Birmingham, Alabama rocked our entire nation to the core, and from the memory of the four little girls that were lost in this unimaginable tragedy came “Four Women” — along with Simone’s other activist anthems like “Mississippi Goddam,” “Old Jim Crow” and “To Be Young, Gifted and Black.” Through storytelling and song, Nina Simone: Four Women reveals how this iconic chanteuse found her true voice — and how the “High Priestess of Soul” helped define the sound of the Civil Rights Movement.
